I am gonna be honest.If you are looking for an amazing drama then this not the one.The plot and dialogues were not good.They revealed who the ghost is too early.But I don't regret watching it.I think it is supposed to be a quick and fun thing to watch.The idols are very talented and they did a good job with what they were given.Their friendships and bond is super adorable.I would love to see them in more dramas where they are given a chance to teuly show their acting skills.Also there were some funny moments.Overall if you are treasure stan then you should definetly watch it.
